Do you know where jsonld discussions are at? I'm having trouble finding a mailing list. ________________________________________ From: Andy Seaborne <[email protected]> Sent: Thursday, January 4, 2018 2:34 PM To: [email protected] Subject: Re: JsonLD @vocab Adam, In the first instance, this seems like something to raise with the jsonld-java team to find out if that is intentional. Could you open a discussion issue there? IIRC empty prefix and the base are mixed up in JSON-LD. Andy On 04/01/18 03:34, Adam Jacobs wrote:The @vocab prefix is dropped by Jena when parsing JsonLD. An empty prefix is correctly translated into @vocab during serialization, but is lost during deserialization. Below code demonstrates the point. public static void main(String... args) { String base = "http://www.ns.com/base/";; String prefix = "http://www.ns.com/prefix/";; Model m = ModelFactory.createDefaultModel(); m.setNsPrefix("", base); m.setNsPrefix("prefix", prefix); m.add(m.createResource(base + "foo"), m.createProperty(prefix + "bar"), m.createResource(base + "baz")); String jsonLD = serializeJsonLD(m); System.out.println(jsonLD); InputStream in = new ByteArrayInputStream(jsonLD.getBytes()); Model m2 = ModelFactory.createDefaultModel().read(in, null, "jsonld"); System.out.println(serializeJsonLD(m2)); } public static String serializeJsonLD(Model m) { OutputStream out = new ByteArrayOutputStream(); m.write(out, "jsonld"); return out.toString(); } From what I can see, jsonld-java is intentionally ignoring the @vocab key at line 277 of Context.java. https://github.com/jsonld-java/jsonld-java/blob/master/core/src/main/java/com/github/jsonldjava/core/Context.java I'm not sure if this is a bug in jsonld-java, or intentional behavior from a jsonld perspective that Jena should work around e.g. in JsonLDReader?
